With rum, Irish whiskey and bourbon on the rise, Schweppes will add a mixer for dark spirits to its premium 1783 range this Autumn.

Schweppes Muscovado is a new style of mixer created by bartenders specially to enhance dark spirits and has flavours of vanilla, caramel and butterscotch.

"The new Muscovado variant highlights how 1783 is more than a range of tonics, but instead a portfolio of naturally flavoured premium mixers with the same long-lasting effervescence associated with classic Schweppes," explained Simon Harrison, customer marketing director for the UK at distributor Coca-Cola European Partners (CCEP).

"Expertly crafted with guidance from mixologists and drink experts, the full 1783 range is designed to help licensees and bartenders deliver interesting, great tasting, mixed drinks and cocktails for consumers to explore."

The mixer will come in a 200ml bottle and will hit the market this September.

CGA figures show that sales of dark and flavoured rum are in strong growth and demand for whisk(e)y is also on the up, with sales increasing by 2.5 per cent.
